Am I high? White teas seem to me to be rather delicate

I've had similar experiences to a number of those here. Keep in mind, I'm very new to tea. I've found I get a very nice, light sweet tea when I steep at about 70-75*c for 1min. I'm on my 5th infusion in a 100ml pot right now. Still enjoying the same great cup it seems.

Next time I have some on hand, I will try it hotter, but somehow over the years I have been lowering the temp, not increasing it. I think my tastebuds are telling me something about my presonal tastes.

I like it lighter, delicately sweet ... and lots of steeps. I don't go after intensity which I would suspect the higher temp would bring out?

Colder tends to bring out the flavors in layers, but probably lacks the majority of the healthy components that create the later astringency.

Hotter has been shown in studies to release the most poly-cyclics, and therefore the balance is between getting the most out versus degradation due to heat.... here of course you will get a stronger, more bitter, more astringent brew.

To get the best flavor profile, you have to brew cooler with many steeps to see all the individual layers, then choose a temperature and time combination that overlaps the layers you think will taste best together.... this process applies to all teas technically.
